Long Zihan said: "But you just said that the deceased's left ventricle had a penetrating injury. ”

Chu Yiren nodded and said: "It is precisely because of this that one-eighth or one-tenth of the blood of the deceased is pressed out of the circulatory pipe, causing the amount of circulating blood to gradually decrease, causing hemorrhagic shock, and finally death." ”

After saying so many words in one breath, Chu Yiren picked up the water cup and took a sip of water.

When everyone thought she was finished, she continued: "However, an anomaly was found in the deceased's head. ”

Long Zihan frowned and asked, "What?"

The Chuyi replied: "The deceased had been hit in the head before he was mortally wounded. ”

Mo Bei couldn't help the curiosity in his heart, and hurriedly asked, "What's the matter?"

Chu Yiren said: "The deceased was hit with a hard object on the occipital part, which seems to be a club, but the injury is not serious. ”

Long Zihan asked, "What about the degree?"

The Chuyi replied, "Dizziness, pain, or coma." ”

Zhao Xiaohu said: "The murderer will first hit the victim in the back of the head with a stick, and then stab him to death with a dagger, isn't it a bit too much?"

Long Zihan said simply and clearly: "It's not the same person. ”

Erin analyzed: "The purpose of the two is different, the person who hit the head is obviously very timid, and then looking at the loss of property on the deceased, it is speculated that the person who hit the head may have robbed money and injured people." And the knife that stabbed Wang Honglan to death was so deep, the purpose was very obvious, it was to kill people. ”

After speaking, she looked at Wang Xiaoguang.

Wang Xiaoguang said: "There are several footprints found at the scene that cannot be found by the owner, and there are fingerprints on the deceased's clothes and pockets. But this fingerprint is very special. ”

Long Zihan asked, "What do you say?"

Wang Xiaoguang replied: "The reason why I can leave so many and so clear fingerprints is because the other party's hands are rubbed with allantoin cream." ”

"What's that for?"

"Allantoin cream has physiological functions such as promoting cell growth, speeding up wound healing, and softening keratin, and is a good healing agent and anti-ulcer agent for skin wounds. A medicine that promotes the healing of skin ulcers has a healing effect on the skin. It is used for psoriasis, dry skin, chapped hands and feet, scaly skin diseases, skin ulcers, acne and other diseases, all of which have good curative effects. ”

Listening to Wang Xiaoguang's words, Zhao Xiaohu said impatiently: "Speaking of which, isn't it just an ointment to treat skin diseases?

The corners of Wang Xiaoguang's mouth twitched slightly and said, "Uh...... So to speak. ”

Long Zihan asked, "Are there any other clues?"

Wang Xiaoguang nodded and said, "A piece of brown leather was found in the gap between my deceased's fingernails, which was confirmed to be sheepskin by testing. Chemicals such as greases, organic solvents and water repellents are also found on the leather. ”

Long Zihan asked, "What is it?"

Wang Xiaoguang replied: "It's leather clothing maintenance oil." ”

Zhao Xiaohu said with some surprise: "Maintenance oil?

Wang Xiaoguang nodded and said, "Yes, but most poor people like us have never heard of it, let alone bought it and used it." ”

The corners of Zhao Xiaohu's mouth twitched, and he said, "No, no, No, Young Master Wang, you have exalted us." If you are poor, we will come out of the slums. ”

Mo Beidao: "Su Yongzhang, who has been pestering Wang Honglan recently, is in the transportation business, not to mention that he has a lot of money, but also has a lot of money. It shouldn't be difficult to buy leather clothing maintenance oil or something. ”

Liu Yuanheng said: "Don't worry, I have already sent someone to invite, and I will be able to meet this Su Yongzhang later." ”

Long Zihan looked at Erin and asked, "Did you go to Wang Honglan's house and find anything?"

"We asked Wang Honglan's neighbors, she lives alone, goes out and returns late every day, and because of her profession, the neighbors don't have much contact with her. We found a lot of photos of her heavier, looking at the photos she is a very happy person with life. ”

Long Zihan took Wang Honglan's photos, looked at them one by one, and said: "Hangzhou West Lake, Suzhou Garden, Tongxiang Wuzhen, Yunnan Dali ......"

Looking at the past one by one, the photos above are some travel photos taken by Wang Honglan at different ages, different seasons, and different locations.

Erin said: "I have seen these photos, and Wang Honglan is smiling very happily in the photos, she should be a cheerful person who is more eager to live freely. ”

Knowing that Erin must have something to say, Long Zihan nodded and motioned for her to continue.

Erin said: "And such a person who longs for independence and freedom actually wants to settle down and is ready to buy a house and settle down." ”

"Oh?"

"We found several business cards from real estate agents in Wang Honglan's drawer, as well as recent newspaper sales information," said Erin. ”

Long Zihan asked, "Where is she going to buy a house?"

Erin replied: "I think she is focusing on the old town of East Street, and I guess it's because the houses over there are cheaper." ”

Liu Yuanheng said: "I have checked her assets, and it is indeed enough to buy a house." ”

Long Zihan nodded and ordered: "Go check according to this line, and in addition, go to various pawnshops to inquire and see if you can find it." ”

Liu Yuanheng nodded and replied, "Okay!"

"Mo Bei, Zhao Xiaohu, you are responsible for the line of allantoin cream, see if there is any hospital, pharmacy, or clinic near the origin song and dance hall that has sold this medicine recently, and check the patient's information. ”

The two responded in unison: "Yes!"

"Erin, there are only three leather clothing stores in the urban area of Shanghai, and the people who can afford it are not ordinary people, you check the customers who buy brown sheepskin leather clothes and buy maintenance oil at the same time, see if you can find anything. ”

Erin nodded and said, "Yes." ”

Just then, there was a knock on the door.

"Enter. ”

A police officer pushed the door in and said, "Long Shao, Su Yongzhang is here......"

When I came to the living room, I heard Su Yongzhang crying: "******, I spent so much money on that little goblin, and this person hasn't arrived yet, why did he die." ”

How sad it was for people to die and not see him, he was so distressed about money that Long Zihan couldn't help but be bored.

Long Zihan walked in and looked at his long shirt and horse coat, the standard old man's dress. However, there is also a bright red on the neckline of the horse coat, which looks like the lipstick has been rubbed on inadvertently.

Long Zihan politely stretched out his hand and said, "Hello Mr. Su." ”

Su Yongzhang stretched out his hand and shook his hand to show politeness.

Long Zihan paid attention to his hand, and it was smooth, indicating that his hand was not sick.

Subsequently, Long Zihan did not open the topic directly, but said like chatting: "I thought Boss Su was a fashionable person, but I didn't expect it to be so stable." ”
